Originally intended as the class workbook for the Serum Making Class at the Soapmaking Studio in Lemon Grove, California, this book serves as a standalone instruction manual for making serums if the reader is already familiar with good manufacturing practices for home crafters, weighing ingredients accurately on a scale, and home cosmetics crafting in general. A valuable resource when making serums, this book has a chapter detailing the different active ingredients, their Skin Deep database scores, common uses, appropriate quantities, constraint parameters, and perceived benefits. This book includes a recipe and instructions for making a concentrated serum base. It then breaks into different chapters of recipes and instructions for making the serum base into the following finished products: Facial serums, aloe vera gel, hand sanitizer, gel eye shadow, gel eyeliner, and mascara. The detailed material includes packaging and labeling suggestions. With Serum Making Class, it is easy to start making your own facial serums and personalized cosmetics with beneficial active ingredients!
